After the switch from 3.5 to 4.0 my audio is a bit choppy. I am using HLE settings. The games I have tested out are Kirby, lost in shadow, mario kart. Lost in shadow and mario kart was a bit choppy played about a 5 mins into the game, they were choppy. Kirby seemed to be unaffected. My FPS was at 60, so gameplay itself is fine.
